What do we know about the mountain gorilla’s background? Their scientific name is Gorilla berengei berengei. Mountain gorillas reside in high altitudes, so they have thicker fur than many other great apes. When you see these human-like creatures, some ranging up to 5.5 feet tall and 440 pounds, you think, there’s nothing that could stop this beast! Sadly, you couldn’t be any further from the truth. Mountain gorillas, from those in the Virunga Mountains to Uganda, are endangered. These unique creatures deserve to survive.
